HERBERT H. HULL, OF CLEVELAND, OHIO, ASSIGNOR TO THE HULL KEY CANCOMPANY, OF CLEVELAND, OHIO, A CORPORATION OF NEW J ERSEY'.

FRICTION SPECIFICATION forming part of Letters Patent No. 742,325, datedOctober 2'7, 19031 Application filed November 24, 1902.

To aZZ whom it may concern.-

Be it known that I, HERBERT H. HULL, a

citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Friction-Top Cans, of which the following is a full,clear, and exact description, reference being bad to the accompanyingdrawings.

The object of the invention is to provide a so-called friction-top canwhich shall be cheap in construction and neat in appear; ance and fromwhich when the cover is removed one may easily remove substantially theentire contents.

The invention consists, generically, in a teristics of constructionillustrated in the drawings and hereinaftendescribed, all of which aredefinitely pointed out in the claims.

In the drawings, Figure 1 is a side elevation, partly in verticalsection, of a frictiontop can embodying my invention in its best form;and Fig. 2 is a similar view of a modification of the invention.

Referring to'the parts by letters, A represents a cylindrical can-body,which is closed at its lower end in the usual or any suitable manner.The open upper end, or neck of this can-body is nearits edge, as at a,of slightlygreater diameter than it is in the zone a just below saidedge. This effect may be produced by enlarging the diameterof the necknear the edge or by reducing the diameter of the neck in the zone justbelow said edge. In the best construction, however, the can-body isformed with a short neck portion 0. of smaller diameter than the body,thereby forming an annular shoulder a Close to the upper edge of thisneck is a small outwardly-extended bead a.

The cover B is provided with the usual mar- Serial No 132,565. (Nomodel.)

ginal flange b,and the lower edge of this flange is rolled inward toform the internal bead-b. The internal diameter of this bead is slightlyless than the external diameter of the bead a on the neck of the body,wherefore it is necessary in putting the cover onto the body to springthem relatively. This may be done by the application of sufficientpressure when the oppositely-beveled edges of these beads are broughtinto contact. After these beads have passed one another the resiliencyof the metal will cause it to return to its normal 7 condition, andthereby tolock the cover upon the body, so that their separation is moreor less diflicult. The height of the flange b of the cover is such thatwhen the cover and can are locked togetheras specified the top edge ofthe neck of the can will be drawn against the top of the cover, or,better, against a gasket C,whose edge lies between the bead b and thecover-top, and it is thereby held in oper ative position.

The construction shown in Fig. 2 is sub-' stantially the same as thatshown in Fig. 1, except that the extreme upper edge of the neck isturned inward. The only purpose of so turning in this top edge is topreserve the gasket, which otherwise might be out by the raw edge of themetal. This construction (shown in Fig. 2) is the best construction forthe reason stated, although it is a trifle more expensive.

Having described my invention, I claim- 1. In a friction-top can, thecombination of a can-body having a neck of smaller diameter than saidbody, said neck being provided with an abru pt,inwardly-directedshoulder,and an outwardly-projecting bead above said shoulder, of acover having a depending flange of substantially the same diameter asthe body, and provided with an abrupt internal bead, substantially asdescribed.

2. In a friction-top can, the combination of a can-body having a neck ofsmaller diameter than said body, said'neck being provided with anabrupt, inwardly directed shoulder at right angles with saidbody and anoutwardlyprojecting bead above said shoulder, of a cover having adepending flange of substantially the same diameter as the body andprovided at its lower end with an internal bead at substantially rightangles with said flange, substantially as described.

3. In a friction-top can, the combination of a can-body having a neck ofsmaller diameter than said body, said neck being provided with anabrupt, inwardly-directed shoulder,and an outwardly-projecting beadabove said shoulder, of a cover having a depending flange ofsubstantially the same diameter as the body, and provided with an abruptinward-rolled bead, and a gasket between said cover and said neck,substantially as described.

4. In a friction-top can, the combination of a can-body provided with aneck, said neck being provided with an inwardly-projecting portion, anoutwardly projecting portion forming a bead above saidinwardly-projecting portion, an inwardly and upwardly projecting portionabove said bead and a portion projecting downwardly from saidlast-mentioned portion, of a cover for said can having a dependingflange provided with an internal bead, and a gasket adapted to rest onthe upper end of the neck and to be clamped in contact therewith by thecover, substantially as described.

5. In a friction-top can, the combination of a can-body provided with aneck of smallerdiameter than said body, said neck being provided with anabrupt inwardly-projecting portion, an outwardly-projecting portionforming a bead above said inwardly-projecting portion, an inwardly andupwardly projecting portion above said bead and a portion projectingdownwardly from said last-mentioned portion, of a cover having adepending flange of substantially the same diameter as the body providedat its lower edge with an abrupt internal bead and a gasket adapted torest on the upper end of the neck and to be clamped in contact therewithby the cover, substantially as described.

6. In a friction-top can, the combination of a can-body having a shortneck of reduced diameter, there being between said neck and body anabrupt substantially horizontal shoulder, said neck having its edgeturned in ward, and having just below said edge a bead whose externaldiameter is slightly greater than the diameter of that zone of the neckwhich is just below said bead, combined with a flanged cover whoseexternal diameter is substantially the same as the diameter of the bodyand which is provided on the lower edge of its flange with an abruptinwardly-rolled bead.

In testimony whereof I hereuntoaffix my signature in the presence of twowitnesses.
